Question

find the quadratic equation whose roots are-5 and -3​

Answer 1

Answer:

x²+8+15

Step-by-step explanation:

roots = -5, -3

sum of roots = -5+(-3)

= -8

product of roots= -5*(-3)

=15

reqd. poly. = k[ x²-(sum of roots)+ product of roots]

= k[ x²-(-8)+15]

= k (x²+8+15)

put k=1

ans. x²+8+15
